In pl/sql we have two types of datatypes
1. scalar
2. composite.
In scalar u can store only one value at a time and
ex is a number(10),name char(1) etc.
While in Composite u can store whole row mean if one row
have 3 columns so u can store 3 values in a composite
datatype variable at a time.
Ex. emp employees%rowtype ;
Mean if enployees have 3 columns so in variable emp u can
store 3 values of 3 columns at a time .
